DC4030VL-2 Windows driver README File	     Revision 1.01


     +============================================================+
     |	Microsoft Windows version 3.1 disk driver for DC4030VL-2  |
     +============================================================+

     The files PTICTRL.386 and PTI13.386 are the Microsoft Windows 3.1 disk
     drivers for the DC4030VL-2 Disk Accelerator.

     Use of these two files are optional. Your DC4030VL-2 works without
     the drivers.

     You only need these drivers in the following situations:

     - You want to install TURBO MODE under Windows 3.1.
     - Your DC4030VL-2 is installed as the PRIMARY disk controller with
       more than two IDE drives attached.
     - Your DC4030VL-2 works as the SECONDARY disk controller.

     Please follow the steps below to install the driver for DC4030VL-2.
     The Step 1 and 2 are not needed when only one DC4030VL-2 is installed
     as the PRIMARY disk controller with one (drive 0) or two (drive 0,1)
     IDE drive(s) attached.

     All these operations can be performed under DOS.

     1. Install the DOS driver

	Copy DOSDRV.SYS to your system with the appropriate path.

	Add Device = [drive:][\path\] DOSDRV.SYS in the CONFIG.SYS file.
	Note: This statement most precede any other statement which would
	access the physical drive(s) supported by this driver.

	If your mainboard CPU has a 16-bit external bus (for example, IBM
	486 SLC2), add the /W parameter to the statement

     2. Reboot the system.

     3. Copy the drivers PTICTRL.386 and PTI13.386 to your system in
	the appropriate path.

	It is recommended that the drivers PTICTRL.386 and PTI13.386
	be copied to the Windows SYSTEM directory.

     4. Locate the SYSTEM.ini file found in your Windows directory.
	Check if the following line exist in the [386Enh] section of
	your SYSTEM.ini file:

	[386Enh]
	32BitDiskAccess=ON

	If the statement does not exist, add it into the [386Enh] section.
	If the statement exists, but 32BitDiskAccess is set to "OFF", you
	need to change it to "ON".

     5. Delete the "device=*wdctrl" and "device=*int13" device setting.

	Delete the command lines "device=*wdctrl" and "device=*int13"
	from the [386Enh] section of your SYSTEM.INI file, if they exist.

     6. Install the virtual devices "PTICTRL.386" and "PTI13.386".

	Add the following command lines in the [386Enh] section of the
	SYSTEM.INI file:

	      device=[drive:][\path\]PTICTRL.386
	      device=[drive:][\path\]PTI13.386

	The [drive:] and [\path\] point to the directory that contains
	PTICTRL.386 file and PTI13.386. Note that the setting must specify
	the full path of the device drivers.

     7. If your mainboard CPU has a 16-bit data access bus (for example, IBM
	486 SLC2), add this additional statement:

	      DisksAccessMode= /W

	Adding this additional statement configures the controller to work
	in 16-bit data access mode.  Certain motherboard CPUs have a 16-bit
	external data bus and require this setting (for example, IBM 486
	SLC2). If no parameter is specified, the controller will function
	under the default 32-bit data access mode.

     Start Windows to activate the drivers and the 32-Bit VL-Bus Access.
